PROFILE
Mahesh Aswani
Over six months, contributed to the intel/pti-gpu repository by building advanced GPU tracing and instrumentation features using C++, Python, and CMake. Developed unified API tracing for Level Zero and SYCL, dynamic symbol loading, and adaptive API loaders to improve compatibility and maintainability. Enhanced tracing granularity and performance analysis by introducing conditional kernel launch recording and synchronization observability, while optimizing for low overhead and thread safety in multi-threaded environments. Addressed reliability through targeted bug fixes, type-safety improvements, and regression tests, ensuring robust metrics and stable operation on evolving oneAPI releases. Work emphasized maintainable code, scalable observability, and efficient debugging workflows.

Mar 1, 2025March 2025 summary for intel/pti-gpu focusing on PTISDK tracing and synchronization observability. Delivered a feature to monitor and optimize synchronization tracing within PTISDK, with new view kinds for synchronization operations, integration into Level Zero tracing callbacks, and conditional tracing to reduce overhead when specific view kinds are enabled. Also addressed stability by reverting an overhead-related tracing change, simplifying the tracing logic and removing problematic conditional checks.

Feb 1, 2025February 2025 monthly summary for intel/pti-gpu. Delivered unified API tracing support across Level Zero and SYCL within the PTI SDK, including a refactor to a single pti_view_record_api structure for both runtimes and build-system enhancements. Updated CMakeLists to fetch Level Zero loader versions and generate necessary API ID header files, enabling robust tracing and easier maintenance.

Jan 1, 2025January 2025 monthly summary for intel/pti-gpu: Implemented dynamic Level Zero symbol loading and adaptive API loader, enabling runtime adaptation to L0 symbol availability across drivers and hardware. Refactored API loading flow to accept dynamic symbol file paths and updated callback registration to utilize a dynamically loaded API loader. The change improves compatibility, reduces maintenance overhead, and positions the SDK to handle evolving L0 symbol sets without code changes.
